Description
Gebiet der ErfindungField of the invention
Die vorliegende Erfindung betrifft Vorrichtungen zum Spritzgießen von Kunststoffmaterialien, aufweisend zumindest einen Injektor, der eine Düse aufweist, in der eine Verschlussnadel axial beweglich ist, und Betätigungsmittel zum Steuern der axialen Verstellung der Verschlussnadel zwischen einer Schließposition und einer Öffnungsposition, wobei die Öffnungsweite innerhalb eines vorbestimmten Bereichs beliebig verändert werden kann, um den Strom von flüssigem Kunststoffmaterial unter Druck in die Kavität einer Form zu ermöglichen.The present invention relates to devices for injection molding of plastic materials, comprising at least one injector having a nozzle in which a valve pin is axially movable, and actuating means for controlling the axial displacement of the valve needle between a closed position and an open position, wherein the opening width within a predetermined Range can be arbitrarily changed to allow the flow of liquid plastic material under pressure into the cavity of a mold.
Insbesondere betrifft die Erfindung eine solche Gießvorrichtung, bei der die Betätigungsmittel, die die axiale Verstellung der Verschlussnadel steuern, aus einem elektrischen Motor bestehen.In particular, the invention relates to such a casting apparatus in which the actuating means which control the axial displacement of the valve pin, consist of an electric motor.
Stand der TechnikState of the art
Die Verwendung eines elektrischen Motors zum Antrieb der Verschlussnadel des Injektors ist zum Beispiel aus dem Patent
Zusammenfassung der ErfindungSummary of the invention
Das Ziel der vorliegenden Erfindung besteht darin, verglichen mit den in den oben angeführten Dokumenten beschriebenen und dargestellten Lösungen, eine andere und spezifische Lösung bereitzustellen, die es ermöglicht, durch die Verwendung eines elektrischen Rotationsmotors die Genauigkeit der Steuerung der Bewegung der Verschlussnadel zwischen der Schließposition und der Öffnungsposition weiter zu verbessern.The aim of the present invention is to provide a different and specific solution, as compared to the solutions described and illustrated in the documents cited above, which enables the accuracy of the control of the movement of the valve pin between the closing position and by the use of a rotary electric motor the opening position to improve.
Gemäß der Erfindung wird dieses Ziel durch eine Vorrichtung zum Spritzgießen von Kunststoffmaterialien nach dem Oberbegriff des Anspruchs 1 erreicht, dadurch gekennzeichnet, dass das Getriebe zum Umwandeln der Drehung der Welle des elektrischen Rotationsmotors in eine Verschiebung der Verschlussnadel eine Baugruppe aus einer Drehnocke und einem verschiebbaren Schieber aufweist.According to the invention, this object is achieved by an apparatus for injection molding plastic materials according to the preamble of
Gemäß einer bevorzugten Ausführungsform der Erfindung, bei der die Verschlussnadel eine erste Achse definiert und die Welle des elektrischen Motors eine zweite Achse definiert, fallen die erste und die zweite Achse nicht zusammen, und die Baugruppe aus der Drehnocke und dem verschiebbaren Schieber weist einen Rotor auf, der vom elektrischen Motor um eine zur ersten Achse orthogonale dritte Achse in Drehung versetzt wird und mit einem Exzenterbolzen bereitgestellt wird, der in einem Querschlitz eines mit der Verschlussnadel verbundenen Schlittens eingesetzt ist und abwechselnd verschiebbar parallel zur besagten ersten Achse geführt wird.According to a preferred embodiment of the invention, wherein the valve pin defines a first axis and the shaft of the electric motor defines a second axis, the first and second axes do not coincide, and the rotary cam and slidable slider assembly comprises a rotor which is rotated by the electric motor about a third axis orthogonal to the third axis and provided with an eccentric pin inserted in a transverse slot of a carriage connected to the shutter needle and alternately slidably guided parallel to said first axis.
Vorteilhafterweise ist der Exzenterbolzen mit dem Querschlitz des Schlittens gekoppelt, wobei ein Wälzlager dazwischen eingefügt ist.Advantageously, the eccentric pin is coupled to the transverse slot of the carriage with a roller bearing interposed therebetween.
Der elektrische Rotationsmotor kann derart positioniert sein, dass seine Achse parallel und versetzt zur Achse der Verschlussnadel ist, oder derart, dass seine Achse orthogonal zur Achse der Verschlussnadel angeordnet ist.The rotary electric motor may be positioned so that its axis is parallel and offset from the axis of the valve pin, or such that its axis is orthogonal to the axis of the valve pin.
